R8000P V1.4.1.50 Update workaround
Hello All Infuriated R8000P Owners, Ok I found out a solution to the V1.4.1.50 "Lock-Down" as I call it. I too was not able to install updates through, Automatic Update, Manual Update Upload, or...

HOLY SMOKES!!!!!!!!!!! THIS ACTUALLY WORKS!!!
For me, the timings were completely different than what you said.
Here are the steps that I took that worked for me:
- Turn off the router
- Execute the code "nmrpflash.exe -i PORT -f .0.chk"
- Turn on the Router
- Once the Orange light comes on, press the Reset button
- The upload should do its thing.

Folks, I have been battling this for quite a while, and this solution works! Awesome job R8000PFixer ! However, the timing of this thing is really tough. It seems that 3 tries at this solution means you are very lucky. For me, it was 19. AND I found that there are some timing tweaks to get you past errors like "TFTP_UL_REQ" timeouts.
So here are my 19 cents:
1) get Nmrpflash installed
2) get NPcap installed, (gotta have it)
3) For me, I did not need to have the ping window going to get the nmrpflash -L to give me the correct adapterID (mine was net7)
4) The adapterID is case sensitive in the nmrpflash command
5) The LED switch was left on
6) Use router port 1 of the router
7) Change your wired IP address to be static but if you have lots of devices pick a number much higher than 192.168.1.10
8) If you can, run your CMD window as admin, to avoid the admin prompt ever time you try this.
9) Then go to c:\users\your_username\desktop
10) copy your firmware file there and rename it to something short, like R.chk
11) turn off the router
12) in the CMD window type the command below, using your adapterID where I have net7. The -t and -T affect longer handshakes
13) nmrpflash -v -i net7 -f R.chk -t 10000 -T 10000 and press enter
14) when the command starts, power on the router and right when you see the power light press the reset button for anywhere from three to seven seconds, and on some tries, even try pressing the reset button before the power light comes on.
15) you will get lots of fails, and if the white lights come on, or the command times out, go back to step 11
16) Suddenly, on your last pass, the timing works out and the R.chk file loads. Don't get impatient as it runs a while.
17) Wait for the instruction to "Reboot your device", and let it sit a minute. Then reboot it.
18) You may have to go back and change your wired static IP back to non-static, or windows may choke on it
19) You can then reconfigure your router from scratch, rebooting several times before it is how you need it
20) Your firmware will indeed be updated, and the nightmare is over.
21) Interesting reading here: https://github.com/jclehner/nmrpflash and consider a donation. This fix is worth it!

Hi everybody
I was struggling a while before I got it worked. In my case, the scenario was even more straightforward. The clue was to add IP addresses explicitly and no reset button at all
Precondition:
ETH connected to router port1
Local PC IP address: 192.168.1.10
Interface name: net12
File with firmware name: a.chk
Scenario:
1. Switch router OFF
2. Send command from PC:
C:\ppp>nmrpflash.exe -v -i net12 -a 192.168.1.1 -A 192.168.1.10 -f a.chk
3. Switch router ON check out the terminal:
Waiting for Ethernet connection (Ctrl-C to skip).
Adding 192.168.1.10 to interface net12.
Advertising NMRP server on net12 ... /
Received configuration request from 10:0c:6b:13:4e:7d.
Sending configuration: 192.168.1.1/24.
Received upload request without filename.
Using remote filename 'a.chk'.
Uploading a.chk ... Warning: TFTP block rollover. Upload might fail!
OK (53346382 b)
Waiting for remote to respond.
Remote finished. Closing connection.
Reboot your device now.
Powercycle this **bleep** and job is done
